Myntra的BCP/DR之旅。业务连续性计划

Myntra has datacenter in region A . For diaster recovery (DR), Myntra got another datacenter in the region B. So region B became our DR region for region A.

Myntra在A区有一个数据中心。为了进行灾难恢复（DR），Myntra在B区有另一个数据中心，因此B区成为A区的灾难恢复区。

If things go offtrack, it can lead to the unavailability of one whole region. So having at least two data centres in two different regions for business continuity makes sense.

如果事情偏离了轨道，就会导致整个地区无法使用。因此，在两个不同地区拥有至少两个数据中心以保证业务连续性是有意义的。

We were using region A datacenter for serving production traffic. Region B datacenter was used for realtime state replication of databases and also to keep backup of databases.

我们使用区域A的数据中心为生产流量提供服务。区域B数据中心用于数据库的实时状态复制，也用于保持数据库的备份。

So if region A is unavailable due to disaster, we can use backup state from region A to restore state in region B and provision stateless services in region B and then enable the production traffic in region B.

因此，如果区域A因灾难而不可用，我们可以使用区域A的备份状态来恢复区域B的状态，并在区域B提供无状态服务，然后在区域B启用生产流量。

For diaster recovery, we need to do Business Impact Analysis of all the tech systems and need to arrive at the acceptable RTO and RPO thresholds.

对于灾难恢复，我们需要对所有技术系统进行业务影响分析，并需要得出可接受的RTO和RPO阈值。

RTO- Recovery Time Objective- Acceptable time duration threshold to restore the business function after the diaster event

RTO--恢复时间目标--在灾难事件后恢复业务功能的可接受的时间长度阈值。

RPO- Recovery Point Objective- Acceptable threshold for how back you will go back in time before diaster to restore data in usable format.

RPO--恢复点目标--可接受的阈值，即在灾难发生之前，你将回到多远的时间，以可用的格式恢复数据。

BCP/DR first phase

BCP/DR第一阶段

We wanted to do first iteration to move couple of services from region A to region B with production traffic.

我们想做的第一个迭代是将几个服务从区域A转移到区域B，并带有生产流量。

We wanted to solve two things with this:

我们想通过这个解决两件事。

Do the ground work on production infra and network infra connectivity and platform services setup in both the regions and build necessary automation to move services from one region to another region
为两个地区的生产基础设施和网络基础设施连接以及平台服务设置做基础工作，并建立必要的自动化，将服务从一个地区转移到另一个地区。
